I recently stopped using the close up tooth paste.because close up is not approved by ADA( American dental association) .if they didnt approved it we can understood that there is something problem in that toothpaste which may harm us.so its better not to use it.it is not having good cleaning effect.flavor is good.due to giod flavor all of us will love this tooth paste.especially children will love the paste.but it is having high oral impact.over all benefit is not good.so avoid using this close up tooth paste.
